ATTACHMENT FOR RAILROAD-BRAKES.

Specification of Letters Patent.

Patented Sept. 1'7, 1907.

Application filed May 31. 1907. $erial No. 376,638.

To all whom it may concern:

Be it known that I, GEORGE O. WYLAND, a citizen of the United States, residing at Greensboro, in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Attachments for Railroad-Brakes; and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

The present invention has reference to safety attachments for air and other car-brakes and the object thereof is to provide a simple and practical means whereby the brakes are automatically set in case of derailment or any unusual movement of the truck thus avoiding accident.

The invention consists in an attachment constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 of the drawings is a side elevation of a portion of a freight car and truck showing my improved attachment applied thereto. Fig. 2 a perspective view of the attachment on an enlarged scale. Fig. 3 a sectional view of the attachment showing it in an applied position.

In the accompanying drawings A represents a portion of a freight carand B the truck to which the wheels 0 are suitably connected to show the application of my invention thereto, the ordinary air-tubes of the train being shown at a b.

The attachment consists in part of the hanger D suitably connected to the usual bolster c or to any other part of the truck found most convenient, as shown in Fig. 1 of the drawings.

The yoke consists of two sections E F joined together by a suitable sliding connection which in the present instance consist of elongated slots d in overlapping ears or projections e at the ends of each section and suitable headed pins f passing through theslots whereby the sections will move on each other as shown in Fig. 3 of the drawings. The yoke comprising the two hinged or pivoted sections is in the form of a horizontal collar in contradistinction to the pivoted and hinged levers heretofore in use and is operated from the under side of the car-truck and possesses many advantages over the lever arrangement in that it is much simpler and consequently less liable to get out of order besides its operation is more certain, the weight of the yoke-sections alone automatically bringing them to their normal position on account of the yoke being disposed horizontally: The sections E F are suitably hinged to a baseplate G which is secured to the under side of the car as shown in Fig. 1 of the drawings or to any other object found most convenient.

One of many means that may be employed for pivoting the sections of the yoke to the base-plate resides in the lugs 9 depending from the under side of the baseplate G and are suitably pivoted to the yoke sections as shown in Figs. 2 and 3 of the drawings. The base-plate G has a cential opening it to give free play to the end of the operating arm H during the rocking motion of the truck, said arm projecting from the hanger D and extends upward into the yoke, as shown in Fig. 1 of the drawings.

The sections E F are angular or fiat sided as shown at i but may be of any other suitable form or shape as found most preferable, as the form shown is not essential to the successful operation of the attachment. The sections E F of the yoke have inwardly projecting contact flanges j against which the operating arm II is brought in contact, as shown in Fig. 3 of the drawings.

The yoke-section F has a suitable lever I to the end of which is attached a chain or other flexible connection indicated at k which may pass over suitable pulleys Z in n and extend to the usual conductors valve 0 wherever located, or any suitable means may be employed for making a connection between the lever of the yoke and any other similar valve regularly placed on the cars or placed there for this special purpose.

In case of an accident causing the displacement of the truck in any manner by forward, backward or twisting movement, the upright arm H of the hanger D which is connected to the bolster a will cause the arm to come in contact with either of the contact flanges j on the sections E F of the yoke. This action of the operating arm I-I against the contact flange 9' will cause the yoke-sections E F to swing open on their pivotal connection, as shown in Fig. 3 of the drawings, raising the lever I which is connected in a suitable manner with the valve or other means for setting the brakes.

The several details of construction herein described may be changed or modified so long as such changes or modifications come within ordinary mechanical judgment and without departing from the essential features of the invention.

Having now fully described my invention, what I claim as new and desire to secure by Letters Patent. is:

1. An attachment for railroad brakes consisting of a yoke in the form of a horizontal collar and constructed of two hinged or pivoted sections and means for operating the sections connecting with the car-truck, and an intermediate means connecting the yoke with the usual means for operating the brake, substantially as and for the purpose set forth.

2. An attachment for railroad brakes consisting of a yoke in the form of a horizontal collar and constructed of two hinged or pivoted sections, an arm connecting with the truck and adapted to engage the yoke to operate it, and an intermediate means connecting the yoke with the means employed for operating the brake, substantially as and for the purpose described.

3. An attachment for railroad brakes consisting of a yoke in the form of a horizontal collar and consisting of two hinged or pivoted sections hinged or pivoted to a suitable base upon the under side of the ear, means conneeting with the truck for operating the yoke, and an intermediate means connecting the yoke with the means for operating the brake, substantially as and for the purpose specified.

4. An attachment for railroad brakes consisting of a yoke in the form of a horizontal collar and comprising two sections hinged or pivoted together, a lever upon one of the sections, an intermediate means connecting the lever with the means employed for operating the brake, and an arm extending from the truck and engaging the yoke for operating the same, substantially as and for the purpose set forth.

5. An attachment for railroad brakes consisting of a yoke in the form of a horizontal collar and comprising two sections, the ends of each section having elongated slots and pins extending through the same by which the two sections are hinged or pivoted together, means connecting with the truck for operating the yoke, .and intermediate means connecting the yoke with the means employed for operating the brake, substantially as and for the purpose described.

In testimony whereof I afiix my signature in presence of two witnesses.
